Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

WhatsApp: +86 18203695377Explain the process of formation of petroleum. Answer Petroleum was formed from plants and animals living in sea. When they died, their bodies settled at bottom of ocean. These get covered with sand and clay. Due to high temperature, high pressure and absence of air. in millions of years, these dead organisms get converted into petroleum
WhatsApp: +86 18203695377The abiogenic petroleum origin hypothesis proposes that most of earth's petroleum and natural gas deposits were formed inorganically. Scientific evidence overwhelmingly supports a biogenic origin for most of the world's petroleum deposits. Mainstream theories about the formation of hydrocarbons on earth point to an origin from the decomposition of longdead organisms, though the existence of ...

WhatsApp: +86 18203695377Petroleum is a fossil fuel that naturally occurs in the liquid form created by the decomposition of organic matter beneath the surface of the earth millions of years ago. These fossil fuels are then refined into usable substances such as petrol, kerosene, etc. It is formed by the combination of hydrocarbons and other substances, mainly sulphur.
WhatsApp: +86 18203695377Fossil fuels are made from decomposing plants and animals. These fuels are found in Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers. More than 50 percent of a piece of coal's ...
WhatsApp: +86 18203695377Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbonbased material approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coalbearing rock units appeared about 290360 million years ago, at a time known as the Carboniferous or "coalbearing" Period.
